TV works fine but computer input gets horizontal tearing after warmup

Both worked fine till one day the computer input started a horizontal tearing after it warms up. TV still works great. I can keep using it as a TV but would like to use it as a monitor also again. Please do not suggest refresh rate or a different pc as a solution, I am not a moron. If there is a part going bad please be as specific as possible in the description and location of the part and if you know of a source for replacement parts. Thanks in advance for the good answers!

    So it sounds like it is one board that handles both inputs, thus probably a expensive part if even available. The unit is a few years old and not in warrentee so I guess it will just be a TV

The good news..
The bad news, The problem is the video logic board inside the monitor. Replacement is the only option and you will have to beg Philips to even get the location of a replacement board if it's not still under warranty. Then sell your first born child to get it.

The explanation.
The video logic board takes all the input signals and sends them to a central processing unit that then sends the signal to the panel itself. If any of the inputs are damaged, then only that section will fail. The monitor input side of your board is dying, most likely due to overheating so collapses after it reaches it's thermal limits.
Chances are the vertical/horizontal input from the video cable is being shorted inside the IC that controls video from the PC. This is a common fault in many Samsung LCD monitors as well.

    There is one upside..

    You can always sell it as a faulty unit on Ebay etc to help cover the costs of a new unit, you may be surprised what people are willing to pay for it still.

Still trying to troubleshoot horizontal lines on my tv. so bad, can't watch. have been in contact with "The Knight". so far no luck.

Hi Steve
The power board to your TV is working fine now. If you're determined to make experiments with it; just carry on!! Replace the boards. one after another, till the fault is rectified.

Sounds like LOT fault. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts.
Do a search by type in the brand name of your device at its search box.

My tv will work fine for say 1 minute then keeps flashing green and shuts off i have looked up the code it says its the D borad thats gone bad is there a wasy i can self fix it.

The "D board" is the flyback transformer, but if it was bad, you would have no picture at all. Here is a proven method to get it to work (for a while....)

The adjustment method is to put the set on a video input with nothing conected
to that input. Turn the screen control up slowly until those fine lines appear
and then down until they just disappear. Do this with all three colors. You
might need to turn one of them down a little initially if the set won't stay on
long enough to get to adjustments. You cannot do the adjustment on a TV station
or on live video input. If the adjustments are too high, the set will turn
bright and shutdown. If they are too low you will never get a picture at

You would want to touchup the adjustments after a warmup of a few
hours, then recheck the next day when cold.

If the adjustments are
successfull and the set stays on but the color reproduction is very poor then
one of the tubes is probably bad.

If you are lucky and everything turns
out OK, you will probably need to do it every year or so.

RCA pix tearing horizontal lines

Get an ESR meter and check all the electrolytic capacitors in the set! I am sure you will find many decoupler and coupling capacitors that are on the edge or too high in ESR.

Power light comes on, followed by a high pitched whine

Hi, If after trying the TV again later and problem persist, repairs are in order. A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube. Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry. Good luck and kind regards.

Advent HT2751A display no good until after 1-2 hour warmup - maybe

After 3 years, I finally decided to open up the TV and do some troubleshooting. Found out the problem, It was a blown capacitor Location C554 Capacitor value is 2200uF 16V - costs about a dollar to replace yourself and the TV works brand new.

Dell 1702FP 'tearing' after warmup

It might be a failing electrlytic or a heat-related issue with a transistor in the power supply, or it may be a problem in the video board. Sounds like will need good old-fashioned component-level troubleshooting.
